INK-ROLLER ADJUSTMENT FOR PRINTINGIMACHINES SPECIFICATION forming part of Letters Patent No. 363,327, dated May 17, 1887.

Application filed October 11, 1836. Serial No. 215,925. (No model.)

To all whom it may concern:

Beit known that we, FREDERICK L. Goss and SAM G. Goss, citizens of the United States, residing at Chicago, in the County of Cook and State of Illinois, have invented a certain new and useful Improvement in Ink-Roller Adjustments for Printing-Machines, and we hereby declare the following to be a full, clear, and exact description of the same.

Our improvement has for its object the provision of means whereby the various ink-rol lers may be readily adjusted singly to bear' with greater or less pressure upon their adjacent cylinders, and to enable them all to be thrown off simultaneously from contact with the cylinders when the press is not running, to avoid the flattening effect upon them of their contact with the cylinders when stationary, this lastnamed object being desirable, owing to the fact that the composition of which the ink-rollers are formed, being soft, if allowed to rest for a sufficient length of time against an object without rotating they become iiattened by the pressure upon the bearing-surfaces, and are thus destroyed.

In the drawings, Figure l shows in end elevation, partly sectional, taken on the line 1 of Fig. 2 and viewed in the direction of the arrow, our improved throw-of and adjusting mechanism for the ink-rollers applied transversely to the printing-press frame, the rollers being represented by dotted lines, in contact with the form-cylinder of a cylinder-press and with the vibrator or ink-drum, the latter and the form-cylinder being represented by dotted lines. Fig. 2 is a broken sectional view taken on the line 2 of Fig. l, and viewed in the direction of the arrow; Fig. 3, a similar view taken on the line 3 3 of Fig. 2, and viewed in the direction of the arrows; Fig. 4, a similar view taken on the line 4 of Fig. 2, and viewed in the direction of the arrow; and Fig. 5, a similar view taken in the line 5`of Fig. 2, and viewed in the direction of the arrow.

A denotes the supporting-frame for the mechanism, and forms part of the frame of the printing-press, which, however, is not shown in the drawings more than is required to indicate its position and that of the form-cylinder and ink-rollers with reference to each other, since it forms no part of our present improvement.

B is a skeleton frame, comprising two vertical standards and a top cross-picce and bolted to the frame A and supporting the various ink-rollers, the mechanisms hereinafter described for adjusting them independently of each other and for throwing them oll simultaneously, and the vibrator or ink-drum which receives the ink applied in the usual manner.

C is this ink-drum or vibrator, journaled at opposite ends -in the frame B and rotating near the form-cylinder D of the press. Inside the frames B are blocks a, having backward-extending iianges a', by which they are bolted on the top of the frame A, and into the face of each is dovetailed, as shown in Fig. 3, a Ilaring block or bearing, E, having a semicircular extension, r, on its lower edge, a semi-cylindrical projection, q, on its inner face, and recessed centrally toward its upper edge to produce extensions p and p, each extension p and p being also provided on its outer edge with an ear, o, having a threaded opening containing a screw-pin, o', provided with a wing-nut, o,` for a purpose hereinafter scribed.

Below each block E is a cam, F, in contactl with the semicircular projection 1" on the block, and supported to be oscillatcd upon a rock-shaft, F, between the frames A and blocks a, and provided at one projecting eX- tremity with a hand-lever, F2, Fig. 2. Thus by rocking the shaft F the cams F, under the blocks E at opposite ends of the frame B, raise and lower the blocks as desired, and support them in their adjusted positions.

From the nature of the views -selected to illustrate our improvement, only one side of the apparatus is shown. stood, however, that the adjusting mechanism hereinbefore and hereinafter described is also provided at opposite ends of the ink-rollers. Thus, of the parts already described, the

frame B, iianged block n, reciprocating bear- 95 p ing E, and semi-cylindrical extension q are duplicated on the side not shown. On theinner side of each block E, ou their fiat sides,

It will be under- 9o extending, respectively, along the parts p and p', are semi-cylindrical boxes G and G', provided with extensions m from their flat sides, at which the boxes are pivoted at theirlower extremities to the blocks E, and at their outer edges they carry, respectively the extensions Zand Z', provided with curved slots x to receive the pins o' in the projections o on the blocks E, whereby the boxes G G may be swung to any desired position and fastened therein by means of the wing-nuts o2.

Within the boxes G and G' and the box q, which is stationary, are screws H, extending` through jam-nuts 7c and 7c at opposite ends of the boxes, and carrying at their upperextremities the bearings I, preferably of the form shown, for the inkrollers, which are held therein at their journal ends by suitable Cotter-pins, y. The screw H in each box may be moved longitudinally by proper manipulation of the jam-nuts to adjust the bearing carried by it for the purpose of adjusting the respective ink-roller at its opposite ends, and a transverse screw, H', for each box, rinly holds the screwH in its adjusted position. It will thus be seen that the extreme inkrollers, K and K', may be adjusted with reference to the cylinder D and vibrator C, independently of each other,'to 'bear with greater or less pressure by the swinging motion of which they admit; that these same rollers and the central one, K2, in the stationary'box q, may be independently adjusted at either end by manipulating the screw H to true them with reference to the cylinder D and vibrator, and that the three rollers may simultaneously be moved into and out of contact with the cylinder D and vibrator by rocking the shaft F'.'

On the upper side of each frame B is an ad- 40 justable supporting device for the journal end r-r De of an ink-roller, K, between the cylinder D and vibrator C. It comprises a bracket, L, bolted to the top of the frame B, and carrying, if desired, at its extremity an auxiliary bearing, I', for the journal end of the roller K3, like the bearings I, but stationary, and merely serving the purpose of a rest for the roller K3 when not required to be used, in which to place it in a convenient position for future use when removed from its position shown by the dotted lines in Fig. 1. To the inner side of the bracket L is pivoted transversely a plate,y L', (see Fig. 5,) at e, having an ear like the ears o on the block E, containing also ascrewpin, o', provided with a wing-nut, o2, and upon the plate L' is a box, G2, in form like the boxes G and G', and containing the screws H H', jarnnuts k 7c', extension im, and slotted extension Z, as in the said boxes G G', and pivoted at its extension m to the plate L', whereby an end of the rollerv K3 may be adjusted by the screw H, and the pressure of the roller against the cylinder D and vibrator C may be varied by properly swinging the box G2 and holding it in position by tightening the wmgnut.

When thus adj usted and tightened, obviously tilting downward of the plate L' upon its pivotal bearing will raise the roller K3 out of contact with the cylinder D and vibrator C, and this is effected simultaneously with the removal of the rollers K, K', and K'l from such contact by means of the camrF by connecting the plate L' toward its rear extremity with the block E by a link, M, as shown. Thus whenever the rollers K, K', and K2 are lowered from contact with the cylinder D and vibrator O the roller K3 is raised from such contact, and when the first named rollers are raised into such contact the roller K3 is low ered to act upon the form-cylinder and vibrator. t

It will be noticed that the box Gis shown in Fig. l in dotted lines, the purpose being to avoid obstructing the flaring extension p and permit the ear o to be shown, which, as o on the extension p', is obstructed by the box G'.

What `we claim as new, and desire to' secure by Letters Patent, is-

l. Thecombination, with the formicylinder of a printing press and the ink-drum, of inkrollersv supported in reciprocating bearings, and an ink-roller supported in pivotal bearings connected with the reciprocating bearings, whereby moving the said reciprocating bearings adjusts the ink-rollers supported thereon with reference to the form-cylinder and ink-drum and simultaneously and similarly adjusts the said ink-roller supported in pivotal bearings, substantially as and for the purpose, set forth.

2. The combination, with the form-cylinder of a printing-press and the ink-drum, of inkrollers independently adjustable on pivotal bearings independently adjustable transversely to the rollers and simultaneously adjustable into and out of contact with the formcylinder and ink-drum, substantially as and for the purpose set forth. f
